The netns support currently available on the VyOS CLI is only a
proof-of-technology, we have no real support for any service behind it.
In order to not confuse anyone on the LTS branch we decided to remove the
netns option for interfaces until there is a proper usecase and implementation
available.

After migrating from ISC DHCLIENT for IPv6 to wide-dhcp-client the logic which
was present to update /etc/resolv.conf with the DHCP specified nameservers and
also the search domain list was no longer present.
This commit adds a per interface rendered script to inform vyos-hostsd about
the received IPv6 nameservers and search domains.

interface: T5550: Interface source-validation priority over global value (backport)
|
|
The current implementation is wrong as it searches `master` in the
iproute2 JSON output. It is a worng as it could include bridges
or bonding interfaces
Add the more strict search `info_slave_kind == vrf`

wireguard: T5409: Added 'set interfaces wireguard wgX threaded'
|
|
Using threaded as CLI node is a very deep term used by kernel threads. To make
this more understandable to users, rename the node to per-client-thread.
It's also not necessary to test if any one peer is configured and probing if
the option is set. There is a base test which requires at least one peer
to be configured.

setting
|
|
This is only a cosmetic change so that the default value is properly retrieved
from the defaultValue XML node.

vyos@vyos# run show vrf MGMT processes
2282 sshd
There is no dhclient process running in given VRF. dhclient complains it can
not send out packets via the given interface (as it's not bound to that VRF)
Aug 02 20:29:54 dhclient[1686]: send_packet: Network is unreachable
Aug 02 20:29:54 dhclient[1686]: send_packet: please consult README file regarding broadcast address.
Aug 02 20:29:54 dhclient[1686]: dhclient.c:3001: Failed to send 300 byte long packet over fallback interface.

Multiple scripts use the same hardcoded path for DHCP client leases in
different direcotries - this can't be worse.

When no-release is specified, dhcp6c client will not release allocated address or prefix on client exit.

netns management for any Vyos interfaces doesn't work past the initial
creation, because Vyos always tries to recreate it/move it into the
netns even though it already exists. Until this is fixed, don't let
anyone even attempt to use this:
set interfaces virtual-ethernet veth10 peer-name 'veth100'
set interfaces virtual-ethernet veth100 netns 'ns01'
set interfaces virtual-ethernet veth100 peer-name 'veth10'
set netns name ns01

This makes netns infinitely more useful as they can be chained together
in many ways to build complex network structures all on the host.

VLANIf('eth0.10').remove() will create and remove the VLAN in one command.
Thus one can ensure when calling remove() on a VLAN it will always
succeed.

Ability to get MTU from DHCP-server and don't touch it per
any interface change if interface 'dhcp-options mtu' is
configured

When removing a VRF from an ethernet interface and adding the interface to a
bond in the same commit led to an OSError: [Errno 16] Device or resource busy!

Directed broadcast is described in rfc1812#section-5.3.5.2 and rfc2644.
By default Linux kernel doesn't forward directed broadcast
packets unless both of `/proc/sys/net/ipv4/conf/all/bc_forwarding`
and `/proc/sys/net/ipv4/conf/$iface/bc_forwarding` are set to 1.

If we have link-local static address and vrf, for example:
set interfaces ethernet eth2 address 'fe80::5200:ff:fe55:222/64'
set interfaces ethernet eth2 vrf 'foo'
This IPv6 address was assigned before vrf, as result after
attaching the intreface to vrf we lose this static linklocal
address
DEBUG/IFCONFIG cmd 'ip addr add fe80::5200:ff:fe55:222/64 dev eth2'
DEBUG/IFCONFIG cmd 'ip link set dev eth2 master foo'
DEBUG/IFCONFIG cmd 'ip addr add fe80::5208:ff:fe13:2/64 dev eth2'
This commit fixes this, the address is assigned after vrf assign
|
|
This extends the fix from 53e20097 ("vyos.ifconfig: T4330: bugfix changing MTU
when IPv6 is disabled") by ordering the execution in a way the Kernel does not
complain.
|
|
Commit f8b3d8999c ("ipv6: T4319: do not configure IPv6 related settings if it's
disabled") moved the MTU configuration part under the code path which is only
run if IPv6 is enabled on the system.
This prevented MTU changes on IPv6 disabled systems.
